Bathynomus giganteus is a species of aquatic crustacean, of the order Isopoda. It is a member of the giant isopods (Bathynomus), and as such it is related—albeit distantly—to shrimps and crabs. It was the first Bathynomus species ever documented and was described in 1879 by French zoologist Alphonse Milne Edwards after the isopod was found in fishermen's nets off the coast of the Dry Tortugas in the Gulf of Mexico.
The Gnathiidae are a family of isopod crustaceans. They occur in a wide range of depths, from the littoral zone to the deep sea. The adults are associated with sponges and may not feed. The juvenile form is known as a 'praniza', and it is a temporary parasite of marine fish. These forms are not larvae; Gnathiidae instead become parasitic during the manca stage. Mancae of the Gnathiidae closely resemble the adult form, however they lack the final pair of pereiopods.
Sphaeromatidae is a family of isopods, often encountered on rocky shores and in shelf waters in temperate zones. The family includes almost 100 genera and 619 known marine species. Within these genera, there are groups that share distinctive morphologies; further research may reclassify these genus-groups as separate families.
Arubolana imula is a species of crustacean in the family Cirolanidae, endemic to Aruba. It was described in 1979 by Lazare Botosaneanu and Jan Hendrik Stock.
Arubolana is a genus of crustacean in the family Cirolanidae, containing the following species:
Arubolana aruboides is a species of crustacean in the family Cirolanidae. It is endemic to Bermuda.
Mexilana saluposi is a species of crustacean in the family Cirolanidae, the only species in the genus Mexilana. It is endemic to Mexico.
Speocirolana thermydronis is a species of crustacean in the family Cirolanidae. It is endemic to Mexico and only known from springs near Cuatro Ciénegas, Coahuila. Its habitat is threatened by irrigation.
Speocirolana is a genus of crustacean in family Cirolanidae. They occur in Mexico from San Luis Potosi northwards and in southern Texas. They are stygobionts. They measure 17–33 mm (0.67–1.30 in) in total length.
Sphaerolana is a genus of isopod crustaceans in the family Cirolanidae, all of which are endemic to Mexico.
Anthuroidea is a superfamily of isopod crustaceans, formerly treated as a suborder, Anthuridea. The group is characterised by "an elongate cylindrical body form, without dorsal coxal plates, and with a uropodal exopod attached to the peduncle proximally and dorsally". There are more than 500 described species in 57 genera, arranged across six families:
Pentidotea wosnesenskii is a marine isopod which lives on seaweed on rocky shores along the British Columbia and Washington coastlines, as far south as San Francisco. It can often be found hiding under rockweed in the intertidal zone, and can be found in depths up to 919 metres (3,015 ft). It was described as Idotea wosnesenskii in 1851, by Johann Friedrich von Brandt, and is named after the Russian biologist Ilya G. Voznesensky. The isopod grows up to 4 centimetres in length and is usually green in colour.
Iais is a genus of isopod crustaceans. Iais species are found in association with larger isopods of the family Sphaeromatidae, usually on the ventral surface of the larger animal, between the pereiopods and on the pleopods. They are native to Australasia and South America, although Iais californica and its host Sphaeroma quoyanum have invaded California, and I. californica was first described from Sausalito, California. Nine species are recognised:
The Cirolanidae are a family of isopod crustaceans, including these genera:
The Microcerberidea are a suborder of isopod crustaceans. They are less than 2 mm (0.079 in) long, and live interstitially. They may be found in the eastern Pacific Ocean, and around the coasts of South America, Africa, the Mediterranean Sea, and India.
Cymothoida is the name of a suborder of isopod crustaceans with a mostly carnivorous or parasitic lifestyle. It contains more than 2,700 described species in four superfamilies. Members of the suborder are characterised by their specialised mouthparts which include a mandible with a tooth-like process which is adapted for cutting or slicing.
Serolidae is a family of isopod crustaceans, containing the following genera :
The Arcturidae are a family of marine isopod crustaceans in the suborder Valvifera. Members of the family resemble woodlice and are found globally in cooler areas in shallow seas.
Aega is a genus of isopods in the family Aegidae, containing the following species:
Speocirolana xilitla is a species of crustacean in the family Cirolanidae. It is known from a cave near Xilitla, San Luis Potosi. The specific name refers to this town. It is the southernmost species in the genus Speocirolana.
